Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and particularly to a rotatable charging pile. Background Art

[0002] The charging pile is similar to a fuel dispenser in a gas station. It can be fixed on the ground or wall, installed in public buildings, residential community parking lots or charging stations, and can charge various models of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles.

[0003] Chinese Patent Publication No. CN219339229U discloses a new energy charging pile with rotatable adjustment. By pulling the pull rod with the handle, the pull rod drives the limit plate and the limit rod to move, thereby releasing the restriction between the mounting plate and the connecting bottom plate. Then, the mounting plate is rotated, and the support column and the universal wheel at the bottom of the mounting plate rotate following the force on the mounting plate. When the charging pile body rotates to the required position, the handle is released, and the limit spring rebounds to push the limit rod into the adjacent limit hole, thereby completing the limitation of the mounting plate. This setting facilitates the user to adjust the direction of the charging pile body according to actual needs, making the charging more flexible and convenient, which is beneficial to improving its applicability and is more time-saving, labor-saving and worry-free.

[0004] However, the support column of this device is rotatably connected to the connecting bottom plate through a bearing. During long-term rotation use and placement, the lubricating oil on the bearing will volatilize. This will not only cause the lubricating performance of the bearing to decline, but in more serious cases, it will even rust. Once the bearing rusts, its rotation will become extremely difficult or even completely unable to rotate, making it difficult to adjust the angle of the charging pile body and affecting the flexibility of the device.

[0049] Specifically, as Figures 4-8 shown in the figure, a fixing shell 302 is arranged above the base 1. The inner wall of the fixing shell 302 is movably connected with the inner wall of the air bag 304. A connecting pipe 305 is fixedly and penetratively installed on the top surface of the storage box 301. The other end of the connecting pipe 305 sequentially fixedly penetrates through the top surface of the fixing shell 302 and the outer wall of the air bag 304 and extends into the air bag 304. The connecting pipe 305 is made of a flexible material.

[0050] In this embodiment: by arranging the air bag 304, the lubricating liquid is sucked from the inside of the storage box 301 through the connecting pipe 305. The arranged storage box 301 is used to store the lubricating liquid.

[0051] Specifically, as Figures 4-8 shown in the figure, one end of the oil outlet pipe 306 fixedly penetrates through the inner wall of the fixing shell 302 and extends to the outside of the fixing shell 302. Check valves are installed on both the oil outlet pipe 306 and the connecting pipe 305. A support frame 308 is fixedly installed on the bottom surface of the fixing shell 302. A communication groove 309 is formed on the top surface of the base 1. One end of the communication groove 309 is communicated with the moving groove 207.

[0052] In this embodiment: through the arranged check valves, the air bag 304 can only suck the lubricating liquid from the connecting pipe 305 and discharge the lubricating liquid from the oil outlet pipe 306.

[0053] Specifically, as Figures 4-8As shown, the outer wall of the support frame 308 is slidably connected to the inner wall of the communication groove 309. An elastic member II 310 is fixedly installed on the side surface of the support frame 308, and the other end of the elastic member II 310 is fixedly connected to the inner wall of one side of the communication groove 309. An adjustment groove 311 is formed through the top surface of the pedal 208. One end of the support frame 308 is formed into a wedge shape, and the side surface of one end of the support frame 308 is slidably connected to the inner wall of the adjustment groove 311.

[0054] In this embodiment: The elastic member II 310 applies an elastic force to the support frame 308, and the support frame 308 drives the fixed shell 302 and the airbag 304 to move, so that the airbag 304 moves to a position where it can contact the extrusion block 313.

[0055] Specifically, as Figures 4-8 shown, circular frames 312 are fixedly installed on the outer walls of multiple support legs 203, multiple extrusion blocks 313 are fixedly installed on the inner walls of the circular frames 312, arc-shaped grooves 303 are formed through the outer walls of the fixed shells 302, and the outer walls of the extrusion blocks 313 are slidably connected to the outer walls of the airbags 304.

[0056] In this embodiment: By arranging the extrusion blocks 313, when the rotating seat 101 drives the support legs 203, the circular frames 312 and the extrusion blocks 313 to rotate, the airbag 304 is extruded, and the lubricating fluid inside the airbag 304 is sprayed from the nozzle 307 to the bearing 202 through the oil outlet pipe 306 for lubrication.

[0057] The specific solution of this scheme is as follows: step on the pedal 208 and move it downward. The pedal 208 squeezes the first elastic member 210 and drives the clamping post 213 to move downward. The clamping post 213 drives the connecting block 214 and the clamping strip 215 to move downward. At this time, the clamping post 213 and the clamping strip 215 respectively move out of the clamping hole 216 and the clamping groove 218, so that the charging pile body 102 can be rotated to an appropriate angle. Then, lift the foot off the pedal 208. The first elastic member 210 applies an elastic force to the pedal 208 and moves it upward, thereby driving the clamping post 213 and the clamping strip 215 to be respectively clamped with the clamping hole 216 and the clamping groove 218, fixing the rotating seat 101 and the charging pile body 102, making it difficult for the charging pile body 102 to deviate in angle, improving the applicability and stability of the device. When stepping on the pedal 208 and moving it downward, the pedal 208 drives the support frame 308 to move through the adjustment groove 311 and squeezes the second elastic member 310. The support frame 308 drives the fixed shell 302 and the airbag 304 to move to the designated position. Rotate the charging pile body 102, driving the rotating seat 101 and the rotating shaft 201 to rotate. The rotating seat 101 drives the support leg 203, the circular frame 312 and the extrusion block 313 to rotate. When the extrusion block 313 rotates, it squeezes the airbag 304. The airbag 304 contracts and discharges the lubricating oil inside through the oil outlet pipe 306 from the nozzle 307 onto the bearing 202, improving the lubrication performance of the bearing 202, making it difficult for the bearing 202 to rust, so that the angle of the charging pile body 102 can be adjusted conveniently and quickly, and improving the flexibility of the device.

[0058] Those of ordinary skill in the art should understand that the discussion of any embodiment above is only exemplary; under the concept of the present invention, the technical features in the above embodiments or different embodiments can also be combined, and the steps can be implemented in any order, and there are many other variations in different aspects of the present invention as described above. For the sake of brevity, they are not provided in detail.
